Nielsen is bringing its Online Campaign Ratings measurement system to Canada in the coming weeks.

The measurement system, which is currently live in the US and UK, measures the audience of online advertising and provides reach, frequency and gross rating point (GRP) metrics as well as demographics such as age and gender. Nielsen’s system uses a patent-pending process that combines traditional Nielsen TV and online panel data with aggregated, anonymous data information for participating online data providers, including Facebook, according to a release.

“Bringing consistent, quality standard metrics to the industry will help advertisers prove the ROI for each dollar spent online and improve ROI for future campaigns,” said Brad Smallwood, VP, measurement and insights at Facebook, in a release. “Nielsen Online Campaign Ratings has helped drive marketers toward an audience-centric buying and selling approach in the US and promises to similarly transform other markets by bringing that same standardization and accountability.”

In addition to launching in Canada, the Nielsen Online Campaign Ratings measurement system is also expanding into Australia, Germany and Italy. The company plans to launch the product in additional markets before the end of 2013.
